The taxonomy and bioacoustics of the elusive crickets from the genus Pendleburyella Chopard, 1969 (Gryllidae: Pentacentrinae).

The taxonomy of poorly known crickets from the genus Pendleburyella Chopard, 1969 (Gryllidae, Pentacentrinae) is reviewed. The type specimens of described species were re-located and re-examined. Based on more recent collections, we describe two new species: Pendleburyella eirmosa sp.

Taxonomy and bioacoustics of scaly crickets (Orthoptera, Mogoplistidae, Mogoplistinae) from Borneo and Singapore.

A species of scaly cricket is described here: Ornebius lupus sp. nov. from the mangrove forests in Singapore.

New species and taxonomic notes of scaly crickets (Orthoptera: Mogoplistidae: Mogoplistinae) from Borneo.

Recent orthopteran surveys in the hyper-diverse Borneo, i.e., Brunei Darussalam and Sandakan in Sabah, allow us to review the scaly crickets from the subfamily Mogoplistinae there.

A taxonomic study on the Bornean and Philippines Sword-tailed Crickets in the genus Rhicnogryllus Chopard, 1925 (Orthoptera: Trgonidiidae; Trigonidiinae).

Rhicnogryllus Chopard, 1925 is a small and relatively unknown group of Sword-tailed Cricket of the subfamily Trigonidiinae. This genus currently comprises 12 species from Asia, Africa (including Madagascar), South America and the Pacific. Species have been recognised by the presence of parallel and elevated veins in both males (which lack stridulatory organs) and females.

New taxa and notes on palm and false-leaf katydids (Orthoptera: Tettigoniidae: Mecopodinae, Sexavaini; Pseudophyllinae, Cymatomerini) from Brunei Darussalam.

As many as 72 species were documented when sampling was conducted in Kuala Belalong in Brunei Darussalam between 2016 and 2017 but this remains non-exhaustive and orthopteran species are still awaiting discovery. Based on new material collected in 2019, two new species of katydids are described here: Segestes nostosalgos sp. n.

New taxa of crickets (Orthoptera: Grylloidea: Phaloriinae, Phalangopsinae, Itarinae and Podoscirtinae) from Borneo (Brunei Darussalam and Sandakan).

Three new species were described from Borneo: Itara (Bornitara) spinosa sp. nov. and Aphonoides duri sp.

A short taxonomic note on the katydids from the genus Cercoteratura Gorochov, 2019 (Orthoptera: Tettigoniidae: Meconematinae), with a key to species.

The tribe Meconematini is a monophyletic and speciose group of slender and predatory katydids from the Indomalayan and Palearctic region (Mugleston et al., 2018). It is especially species-rich from the biodiverse regions of Southeast Asia (Cigliano et al.

New taxa of crickets (Orthoptera: Grylloidea: Gryllinae, Phaloriinae and Pteroplistinae) from northern Borneo (Belait and Sandakan).

Three species new to science of the Gryllid subfamilies Gryllinae and Pteroplistinae are described from Brunei: (1) Mimicogryllus splendens Tan, Gorochov Wahab, sp. nov., (2) Pteroplistes bruneiensis Tan, Gorochov Wahab, sp.

Notes on the taxonomy of poorly known Gryllacrididae (Stenopelmatoidea) from Brunei Darussalam, Borneo.

Gryllacrididae, or raspy crickets, belong to the monophyletic clade Stenopelmatoidea, and have complex taxonomy. Many genera require revision, including the ones from Southeast Asia. Orthopteran surveys in Kuala Belalong, Brunei Darussalam, Borneo led to the discovery of a new species of apterous gryllacridid from Brunei Darussalam: Melaneremus? bellus sp.

New taxa and notes of katydids from the tribe Meconematini (Orthoptera: Meconematinae) from Brunei Darussalam (Part 2).

Based on extended surveys in Kuala Belalong Field Studies Centre, Brunei Darussalam, one new species of Kuzicus is described here: Kuzicus mirabilis sp. nov. This represents the first species described from Borneo for this Asiatic genus.

A new species of Tapiena (Orthoptera: Tettigonioidea: Phaneropterinae) from Brunei Darussalam (Borneo, Southeast Asia).

There are now more than 28,000 described orthopterans globally (Cigliano et al., 2018) and this figure is likely to increase in the future. The same is true for Southeast Asia, where we are still at a stage of discovering species new to science, and this is partly an artefact of incomplete sampling (Tan et al.

New taxa and notes on crickets of the subfamily Landrevinae (Orthoptera: Gryllidae) from Brunei Darussalam, Borneo.

New taxa from the subfamily Landrevinae (Orthoptera: Gryllidae) are expected despite recent work on its taxonomy. Here, two more new species from Brunei Darussalam, Borneo are described: Duolandrevus (Eulandrevus) kawataredoki sp. nov.

New taxa and notes of katydids from the tribe Meconematini (Orthoptera: Meconematinae) from Brunei Darussalam.

Based on the new material collected in Kuala Belalong in Brunei Darussalam, four new taxa of Meconematini katydids (Orthoptera: Tettigoniidae: Meconematinae) are described here. Three new species from three previously known genera are described: Alloteratura (Alloteratura) belalongensis sp. nov.

Taxonomic review of (Orthoptera: Phaneropterinae) with the description of one new species from Brunei Darussalam.

Stictophaula Hebard, 1922 is a genus of katydid from the subfamily Phaneropterinae, and most similar to Arnobia Stål, 1876. A review of the genus Stictophaula reveals 26 species from Southeast Asia. One new species, Stictophaula bruneii sp.
